Question

Considering the expression (5.9 x 10^6) and (3.2 x 10^4) find the differences

Answer 1

The difference between:
`(5.9 * 10^6)\: and \:(3.2 * 10^4)` is
`\mathbf{5.868 * 10^6}`

Explanation:

We need to find the difference between:
`(5.9 * 10^6)\: and \:(3.2 * 10^4)`

We know that 10⁶ means there are 5 zeros in the expression after 9. So,

`(5.9 * 10^6)= 59000000`

We know that 10⁴ means there are 3 zeros in the expression after 2. So,

`(3.2 * 10^4)= 320000`

Now we will subtract them to find the difference

`=5.9* 10^6 -(3.2 * 10^4)\\=5900000-32000\\=5868000`

We can write 5868000 in scientific notation as:
`5.868 * 10^6`

So, the difference between:
`(5.9 * 10^6)\: and \:(3.2 * 10^4)` is
`\mathbf{5.868 * 10^6}`
